shown in this ligure this device 4 prevents assault upon the driver 8 of the vehicle and escape from said vehicle.

The restraining device 4 consists of four main parts, a base Ill, connecting means II, a head I2 and a stud I6. f

The base lil consists of a base plate I8, a boss 26 and a leg shackle member 22. The base plate I8 is provided with bolt holes 24 iixedly 'mounting said base. Fig. 2 shows the base mounted on a vehicle Tioor 26 by bolts 28 through holes 24, holes 30 in the vehicle floor and holes 32 in a retaining plate y34. Boss 20 shown as integral with the base plate is formed with a hole 36 for attachment of the leg shackle member 22 and a bifurcated portion 3B rfor pivotally supporting The leg shackle member 22 consists of an open ring 46 threaded onv each end and a holding nut 42 for holdingthe open ring closed. As seen in Fig. l this member 22 holds a leg shackle 44 thereby restrainingthe feet of a prisoner.

The connecting means II is telescopic in nature having a tube member 48 xedly attached' to the head I2 with a limited amount of movement in relation to a rod member 46 pivotally connected to the base I0. Rod has at its lower end a hole 50 therethrough for receiving pin 52 which is xedly held in holes '54 of the bifurcated portion 38 of boss y20. `This construction allows the pivoting motion shown in Figs. 1 and 2 by n the two different angular positions. To resiliently hold the device at any particular position the bottom of the rod is rounded and has a ratchet for engagement with a spring loaded detent '51 mounted in a bore59` in base plate I8. The detent 51 is biased intofengagement with the ratchet 55 by a spring 6| positioned in bore 59 below the detent 51.

Tube member 48 has a recess end internally threaded to receive bushing 60 whose inner diameter 62 has a sliding engagement with rod 46. Rod 46 has a threaded por-v tion 64 on its upperr end for the attachmentof a guide member 66 which has an internally threaded bore. While no specific means yare vshown xedly attaching guidemember 66 to rod 46, any means desired may be used such as aV kset screw or the peening over of threaded portion ,EL

A'resilient washer 68 in recess 56 is held therein by bushing 60 and a similar washer 10 over threaded portion 64 is held in place by guide member 66. These two washers 68 and 10 serve to cushion the blow when the telescoping members are extended to'their fullest open position.

Head I2 is xedly attached ,to the upper end yof tube member 48. A lower necked down -portion l2 on the head I2 is internally threaded 'at 'I4 to receive the upper part of tube member 48 which is externally threaded. rA set screw 'I6 holds these members infixed relation. The

head member has two main openings therein. a f

stud receivingA opening 'I8 and a lock receiving 56 on its lower.

opening 80. These two openings are connected by a passage 82 for a purpose to be described later.

The lock receiving opening 80 has a key way 84 therein to prevent lock member 86 from turning therein. The lock member 86 is a member consisting of a stud engaging latch 88, a passage guide member 90, a guide and holding collar 92, a guide pin 94 extending from said collar, a. spring guide 96 and a key receiving portion 98. A nut having a circular head |02 and a bore |04 is threaded into the outer internally threaded end of the lock receiving opening 80 for holding said lock member in place. A spring |06 biases lock member 86 into locking position.

As shown in Fig. 4 the stud engaging latch 88 extends into the stud receiving opening 18 for engagement with stud I6 in a manner to be described later. The passage guide member 90 is slideably engaged in passage 82 and the guide and holding collar 92 is biased against the bottom of the lock receiving opening by the spring |06. The guide pin 94 extends upward into the keyway 84 and the spring guide 86 prevents the spring from bending. The key receiving portion 98 extends into bore |04 of nut |00.

The key receiving portion 98 consists of a bore |01 which opens into a bore |08 of a larger diameter. Bore |01 has two diametrically opposed key ways IIO extending into bore |08 to receive key projections II2 on key I I4 (see Figs. 2, 4 and 5). Key projections I|2 extend outward from the stem of the key a total distance greater than the diameter of bore |01 but slightly less than bore |08.

The key I|4 serves to operate lock member 86 by the insertion of the projections I I2 of the key I I4 into the keyways I I0 of the bore |01 and moving the projections into bore |08. The key is then turned to place the projections I|2 behind the face formed at the meeting plane of bores |01 and |08. Movement of the key II4 away from the head moves the lock member thereby removing the stud engaging part 88 from the stud receiving opening 18 to place the head I2 in an unlocked position.

The stud I6 is formed to slideably engage the stud receiving opening 18 and to be held in a locked position by the stud engaging latch 88 of the lock member 84, until released by the key I I 4. A circular tapered portion IIS on the stud rests on the tapered edge II8 of the stud receiving opening 18. This tapered edge I I8 serves another purpose and that is to guide the stud I8 into the opening by having the bottom of the stud rounded as at |20. A notch |22 formed around this stud is for engagement by the stud engaging latch 88 to hold the stud in the head. The notch is formed around the entire circumference of the stud to insure engagement of the latch 88 with the notch when the stud is placed in the opening 18.

The stud I 6 can be iixedly attached to any device desired to be held by the restraining device. In Figs. l and 5 a pair of handcuffs I 24 are shown attached to the stud I6. The handcuffs |24 are of the type having three links |26 between the wrist units. The stud I6 is fixedly attached to one of the links |26 by having :a screw |21 pass through one of the links into a threaded hole in the top of the stud I 6. A tapered pin |29 is xed in a tapered hole through the stud I6 and screw |21 to prevent removal of the screw |21 from the stud. While only one fixing means is shown any type of means desired may be used.

Fig. 6 shows a multiple head unit |28 for use in the event only one base I0 and connecting means I I is available. The unit consists of heads |30, a bar |32 and an attaching member |34.

The head |20 is similar to the head I2, the difference being in the attaching means. Head |30 has a threaded member |36 extending from the bottom to engage an internally threaded bore |38 in the bar |32. The bar |32 contains a number of these bores |38.

'I'he attaching member |34 is formed of an externally threaded part |40 and an internally threaded part |42. Part |40 is threaded into an internally threaded bore |44 in bar |32 and fixed therein by a set screw |46. Part I 42 is adapted to threadably engage the threaded portion 14 of the tube member 48 and be xedly attached by a set screw |48.

Operation In operation, an arresting ofhcer 8 would place on his prisoner 2 a pair of handcuffs |24 having a stud I 6 attached thereto. Now to transport his prisoner it is necessary to use a vehicle, said vehicle having the holding part of the restraining device 4 mounted therein on the floor 26 with the spring loaded detent holding the device in an upright position, out of the way, but easily accessible. It is to be understood that the device may be mounted anywhere desired.

The oliicer 8 seats his prisoner 2 in the vehicle holding the stud I6 and pulling tube member 48 up and towards the prisoner to place the head I2 under the stud I6. The stud is then inserted into the stud receiving opening 18, the round bottom |20 of the stud and tapered edge I I8 of the opening 18 making it easier to place the stud into the opening.

The round bottom |20 of the stud as it moves toward the bottom of the opening 18 engages the stud engaging part 88 and moves it out of the opening against the action of spring |06, as the notch |22 comes opposite the stud engaging part 88 the spring |06 biases the part 88 into the notch to hold the stud I6 in the opening in locked position.

The prisoner is now restrained in the vehicle permitting the officer to perform other duties without fear of the prisoner assaulting him or escaping. The restraining device permits the prisoner a limited amount of freedom with the pivoting and telescopic action of the connecting means I I. In the event the prisoner has on leg shackles these may be fixed to the leg shackle member 22.

When the prisoner 2 is to be removed from the vehicle the key I I4 is inserted into the key receiving portion 98, the projection I I2 of the key passing along the keyways I I0 of the bore |01 and into the bore |08. The key is then turned to place the projection I2 behind the face formed at the meeting plane of bore I 01 and |08. The key is then pulled away from the head I2 thereby removing the stud engaging part 88 from the notch |22 of the stud and out of the stud receiving opening 18 to place the head I2 in an unlocked position. The stud I6 can now be removed from the head freeing the prisoner from the restraining device and making it possible for him to be moved away from said device.
